Greece's stock benchmark was down 1.1 percent as tensions between the country's new left-wing government and the European Central Bank heightened. Greece's new left-wing government is insisting it will stick to its anti-austerity agenda after the ECB tightened the screws on Athens by withdrawing a key borrowing option for the country's banks. Jane Foley, an analyst at Rabobank International, said the ECB decision raised the risk that Greece could be forced into a default.

"Traders are also dusting off the 'Greek crisis' skills they acquired in 2010 and 2011," said Ric Spooner, chief market analyst at CMC Markets in Sydney, Australia. "The key attribute here is the ability to capitalize on the volatility caused by a rapid fire series of conflicting announcements and foreshadowed actions."

The Labor Department reports January jobs data later in the day. Economists estimate that non-farm employers in the U.S. added 230,000 jobs last month, down from 252,000 in December. While some analysts say that the non-farm payrolls data will not be a game changer, the Federal Reserve has emphasized the job market recovery as an important factor when it considers a rate hike.
